Title: Reaction type transmission and reception equipment
Inventor: SETO SHINJI
IPC: H04B7/15
Filed: 1985-11-28
Abstract: PURPOSE:To locate plural sets of transmission/reception equipments being radio relay stations by arranging decentralizingly a transmission/reception equipment to plural locations, and providing an interlocking means to each so that at least two equipments are replied nearly at the same time and the equipments are not interferred mutually. CONSTITUTION:The radio wave sent from a radio transmission station 1 is acquired by a reception antenna A3 (or B8) and a receiver A4 (or B9) detects the input signal wave. The receiver A4 (or B9) supplies a signal to start a transmitter and modulation signal information to a transmitter A5 (or B10) and the output of the transmitter is sent to space from a transmission antenna A6 (or B11) as a radio wave. The transmission/reception equipments A2 and B7 are equipped respectively with interlocking circuits A12, B13 to prevent the mutual interference. In expecting, e.g., the transmission/reception equipment A2 or B7 to act like a radio relay station, either a transmission/reception equipment 2 or 7 relaying a radio wave of a radio transmission station 1 more excellently has only to be operated.

Abstract: PURPOSE:To assure highly effective operation even though operation conditions are changed by providing valves on a line and an expansion line located on the flow side backward a branch point of the line. CONSTITUTION:Upon freezing operation, a refrigerant gas passes through a supercritical expander inlet valve 14 and produces cold by adiabatic expansion work in a supercritical expander 15. Thereafter, the gas passes through a supercritical expansion outlet valve 16a and a heat exchanger 11f, and is partly liquefied by adiabatic expansion in a JT valve 18 and fed to an article 20 to be cooled. Thereupon, a supercritical expander outlet valve 16b and a bypass valve 17 are closed and hence return gas from the article 20 is recovered in its cold through a very low temperature freezer 10 and the heat exchangers 11f-11a, it passes through a low pressure line 4 and is returned to a compressor 1. On the other hand, upon liquefaction operation part of the high pressure gas emanating from the heat exchanger 11e passes through the supercritical expander inlet valve, supercritical expander 15, and supercritical expander outlet valve 16b and flows into a flow pressure line 4 with the remaining high pressure gas passing through the bypass valve 17 and entering the heat exchanger 11f. Thereupon, the supercritical expander outlet valve 16a is closed. Hereby, the supercritical expander can be changed over in conformity with the operation conditions of the very low temperature freezer.

Abstract: PURPOSE:To perform proper control of a slip, by a method wherein, while a slip amount is increased to the set number of revolutions due to deceleration, feed forward control is made on a slip amount control means, and after it is increased to the set number of revolutions, feedback control is performed. CONSTITUTION:A control means 22 contains a deceleration slip region map, and controls a slip amount of a torque converter 1 through a slip amount regulating means 21.

Thereafter, while the number of revolutions is increased to a set value and a vehicle is escaped from a deceleration state, feedback control is effected to converge a slip amount to a target value. This constitution enables proper control of a slip amount.

Title: Semiconductor device and its manufacture
Inventor: YAMAZAKI SHUNPEI
IPC: B82B1/00
Filed: 1996-09-18
Abstract: PROBLEM TO BE SOLVED: To prevent a semiconductor element from a short channel effect caused by micronization and to be able to form a micro-element in a deep sub-micron region by adding impurity elements which expand an energy band width into an impurity region. SOLUTION: Locally added impurities form an energy barrier having a large energy band width in a channel-forming region 103. When oxygen is used as impurities, a barrier is formed by expanding the energy band width. The impurity region which is formed by adding oxygen becomes an insulating high resistance region, having a structure indicated, for example, by SiOx and becomes an electric barrier. That is, a drain side depletion layer is prevented by an impurity region 104 from expanding to a source region 101 or to a lower part of a channel forming region 103, and a drain voltage does not effect the energy condition of the channel-forming region 103. Therefore the prevention of a punch-through phyenomenon or degradation of a sub-threshold property and improvement of a drain withstand voltage can be obtained.

Filed: 1987-10-26
Abstract: PURPOSE:To make it possible to bake up efficiently and uniformly the entire part of a material to be cooked and to downsize a cooking chamber by disposing a rotating device for supporting to rotate a baking net within the cooking chamber, providing heaters at the upper side and the lower side of the baking net, respectively, and inclining the upper side heater so that it is farther from the central part of the baking net than from the end part thereof. CONSTITUTION:A material M to be cooked is placed on a baking net 14 and rotated at a speed of 5-6 times/min, and uniformly heated from the front and back surfaces by an upper side heater 18 and a lower side heater 19. Particularly, when the material M to be cooked is a flat material such as a bread, a quantity of heat proportional to the distance (radius) toward the end part from a rotating shaft 15 for uniformly baking. Since the upper side heater 18 is inclined so that the distance between the upper side heater 18 and the central part of the baking net 14 is shorter than the distance between the upper side heater 18 and the end part of the baking net 14, the quantity of heat afforded to the material M to be cooked from the upper side heater 18 at the end part is stronger than that at the central part in an inverse proportion to the square of the distance. Consequently, it is possible to bake the material M to be cooked uniformly and rapidly. Further, the stracture is simple as a cooking apparatus and the space of a cooking chamber 12 can be reduced.

Abstract: PROBLEM TO BE SOLVED: To quickly warm a converter while suppressing exhausts to a minimum by offsetting a fuel command to a lean direction by a specified amount, and shifting an exhaust gas mixture to the air-fuel ratio of a lean side during a give period after an engine start. SOLUTION: During engine running, a controller 8 calculates a fuel command by dividing the product of an introduced mass flow measure value and a corrected value with the product of a desired air-fuel ratio and a feedback variable. During cooling, an ignition timing is set by using a cold state start table, and then by adding rich offset to a desired fuel amount, the process is moved to an open loop air-fuel ratio operation. Thus, an exhaust gas mixture is shifted to the air-fuel ratio of a lean side, and at this time, a fuel command is corrected based on a corrected value learned from a feedback signal drawn from an exhaust gas oxygen sensor 4 such that the exhaust gas mixture is shifted closer to a pre-measured air-fuel ratio.
